Setting microclimate and working time standards applicable to the use of personal protective equipment
Normirovanie mikroklimata i prodolžitel'nosti raboty pri ispol'zovanii sredstv individual'noj zaščity [in Russian]
28 healthy male volunteers were tested in 349 climate-chamber experiments at temperatures of 10-50°C and relative humidities of 20-100%. Maximum possible levels of stabilisation were determined for rectal temperature, body heat content and heart rate during light, moderate and heavy work. These levels provide criteria for the microclimate within protective suits. The criteria were applied to an air-fed insulating suit. Permissible working times were tabulated for different combinations of effort and microclimatic conditions.

GROT, a personal cooling device
Individual'nyj pnevmatičeskij kondicioner GROT [in Russian]
An air-cooled vest for use in hot workplaces such as deep mines is described. The device is designed for workers expending energy at rates of 10.5-42kJ/min at environmental temperatures of 40°C and relative humidities of 100%. The worker's chest is cooled by perforated plastic panels held in place by straps. The panels are fed with cooled (25°C) dehumidified air from a miniature refrigeration unit hung from the waist. Air and power are both supplied by the compressed-air system of the mine: part of the incoming compressed air (0.4-0.6MPa) is expanded in a heat exchanger to produce cold, while the remainder of the air is passed over the heat exchanger and on to the vest. The refrigeration pack is small enough to fit in a standard battery case; it is connected to the mine's compressed air system by a hose with quick-disconnect fittings. The refrigeration pack weighs 1kg, the vest 0.8kg. A worker fitted with the vest was able to sustain work of moderate effort for 220min at 35-36° and 98-100% relative humidity; a control subject without the vest could tolerate only 80min.

Possibility of maintaining the temperature and work capacity of the extremities
O vozmožnosti podderžanija temperatury i rabotosposobnosti konečnostej [in Russian]
A water-heated suit that did not reach the wrists was capable of maintaining the skin temperature of the wrists and the dexterity of the hands at ambient temperatures of -25 and -45°C when water of 42-43°C was circulated through the suit; the hands and wrists were protected only by thin gloves. The system tested is far more effective than insulating clothing in enabling a worker to perform fine tasks in arctic environments.

A case of allergy to dibutylthiourea caused by divers' footgear
Ein Fall einer Allergie gegenüber Dibutylthioharnstoff in Taucher-Füsslingen [in German]
Un cas d'allergie à la dibutylthiourée de chaussons de plongée [in French]
A case of allergy to dibutylthiourea in divers' footgear is reported. The course of the observed eczema was modulated by the composition of the diving suit worn with the footgear. Dibutylthiourea was identified as a potential allergen by analysing solvent extracts of the rubber foam of which the footgear and suit were made. The allergy was specific for dibutylthiourea: diethylthiourea and diphenylthiourea produced no reaction; this emphasises the importance of identifying and testing specific compounds, rather than treating members of a chemical class as equivalent.

A solution for work in a hostile, radioactive environment: the "Scalhene" air-supplied airtight suit
Une solution au travail en milieu hostile radioactif: la tenue étanche ventilée, type "Scalhène" [in French]
This MD thesis assesses the workload of workers wearing a "Scalhene" air-supplied airtight suit for work in highly hostile atmospheres (in this case in air contaminated with radioactive particles). The ergonomic approach is based mainly on the measurement of heart rate during work. On the basis of the heart rate profiles obtained the job was classified as "arduous" or "very arduous". The medical supervision of the workers and improvements planned for the work are reviewed. Maximum working time should not exceed 2h per day, and the work should be limited to young, healthy workers.

Device for removing dust from workers' clothing
Ustrojstvo dlja obespylivanija specodeždy [in Russian]
Dust is removed from workers' clothing (e.g., mineworkers' overalls) in a cleaning chamber that operates with compressed air (400-500kPa, 480m³/h). Rings of nozzles in the cylindrical chamber blow dust from the garments into a collecting space which is vented into the extractive ventilation system of the plant. The device removes 95% of the dust in garments, and cleans 200 articles/h. Use of the device limits worker exposure to dust between launderings or dry cleanings of their clothes, and can be used where laundering or dry cleaning is not practicable.

Colour scale for objective evaluation of the visibility of safety garments
Cvetovaja škala dlja ob"ektivnoj ocenki signal'noj specodeždy po vidimosti [in Russian]
Presentation of coloured objects to volunteers showed that optimum visibility was associated with hues corresponding to wavelengths of 585-595nm, saturations of 73-87% and reflectances of 30-50%; adequate visibility was obtained with wavelengths down to 582nm, saturation as low as 60% and reflectances of 27-55%. To determine under field conditions whether or not a piece of safety clothing (e.g., roadworkers' coveralls) meets visibility criteria, a colour comparator was devised. The comparator is a card with 30 holes. Next to each hole is a colour patch. Patches corresponding to the optimum values above are located in the centre of the card and demarcated with a line; patches corresponding to adequate but suboptimal colours are placed around the optimal range and separated by a second line from colour patches representing unacceptable levels of visibility. The comparator enables objective monitoring of garments which tend to lose their high-visibility properties through soiling or repeated washing.

O kombinirovannom dejstvii nekotoryh produktov žiznedejatel'nosti pri rabote čeloveka v izolirujuščih sredstvah individual'noj zaščity [in Russian]
The dead-space air inside isolating protective suits contains oxygen, carbon monoxide, methane, phenol and other substances in proportions which vary with the duration and type of work performed. To evaluate the combined toxic effect of various mixtures, 36 experiments were carried out with volunteers performing exercise tests in controlled atmospheres. Biological indices monitored included body temperature, heart rate, respiratory rate and minute volume, energy expenditure, serum cholinesterase activity, etc. Gaseous mixtures containing CO, methane and phenol in proportions of 15, 150 and 3mg% had independent effects similar to mixtures where these proportions were 30, 350 and 5mg/m³, respectively. These concentrations are considered to be maximum permissible ones under the conditions studied.

Physiological evaluation of the resistance to evaporative heat transfer by clothing
Description of a new method to determine the "effective" evaporative resistance of clothing in vivo, which is based on direct measurements of the water vapour pressure gradient between skin and ambient air and of the steady state rate of evaporative heat loss. The technique was used to evaluate the heat transfer properties of 2 types of rainwear and an overall. This method, in combination with partitional calorimetry, enables a direct and simultaneous determination of the resistances of clothing to dry and humid heat loss for both resting and working subjects.

Correlation of urinary pesticide metabolite excretion with estimated dermal contact in the course of occupational exposure to guthion
Exposure to, and absorption of, guthion were estimated in orchardists involved in the mixing, loading, and application with ultra-low volume air blast equipment. Air monitoring and patch techniques were used to estimate exposure, and alkyl phosphate excretion and cholinesterase inhibition were measured to estimate absorption. All workers wore standardised cotton shirts, trousers, long-sleeved coveralls, half-face respirators, gloves, boots, and hats. 8 wore rubberised protective clothing in addition. All workers had quantifiable levels of alkyl phosphates in the 24h urine samples following exposure. A high correlation was found between 48h alkyl phosphate excretion and the amount of active ingredient sprayed. Patches of guthion were found on the skin beneath the clothing by using a fluorescent tracer in the spray tank. The rubberised clothing was not significantly more protective than the heavy coverall. No significant depression of red blood cell or serum cholinesterase activity was found.

Requirement for heat-protective clothing include fire resistance, mechanical strength and moderate weight. Heavy fabric (420-600g/m² optimal) is decisive in heat insulation. Proposed protection criteria: thermal flux density to skin - max. 0.25kW/m², internal temperature - max. 35°C, non-flammable and non-melting properties, all for a minimum of 3s. Review of the characteristics of fabrics for heat-protection clothing: wool, mixed fibres and synthetic fibres. For extreme thermal conditions and where there is a danger of metal spatter, aluminised fabric clothing is advisable, but this is heavy, uncomfortable and impedes movement.

Evaluation of intact gloves and boots for chemical permeation
The permeation of protective gloves and boots by 1,4-dichloro-2-butene (DCB) was evaluated using intact samples and patch tests of the constituent material. Gloves constructed of neoprene or PVC on cotton, neoprene, NBR and Viton were exposed to a spray of DCB. The amount penetrating the glove, and contained in a carrier gas, was determined at 15min intervals using charcoal sampling tubes. Evaluation of the protection afforded by the gloves, using this method, correlated well with breakthrough times determined on patches of glove material. The feet of whole boots constructed of neoprene or PVC were immersed in DCB and the penetration determined by means of DCB in a carrier gas at 1h intervals up to 6h. Patch tests of boot material did not correlate well with permeation measurements because of thickness variations.

Effect of heat stress on physiological factors for industrial workers performing routine work and wearing impermeable vapor-barrier clothing.
Body temperature and pulse rate were measured in 10 workers wearing various types of vapour-barrier (VB) clothing and 25 controls, performing routine work at high ambient temperatures. Workers wearing VB clothing reached an extrapolated oral temperature of 37.6°C at a 2.8°C lower WBGT index than the control subjects. When work duration in VB clothing was >45min, the oral temperature rose above 37.6°C. There were no recovery pulse rates about 65% of the time after wearing of VB clothing for 15min. The implementation of engineering and administrative controls and use of a vortex-cooled air suit significantly reduced the stress of working with VB clothing at high temperatures.

Penetration of americium into polymers used in protective coatings and in personal protective equipment
O pronikanii americija v glub' polimernyh materialov, primenjaemyh dlja zaščitnyh pokrytij i sredstv individual'noj zaščity [in Russian]
A method is given for the calculation of the penetration of ²⁴¹Am beneath the surface of polymers in the presence of large amounts of ²³⁹Pu. An increase in acidity of the suspension solution promotes penetration, while the amount of Am absorbed considerably decreases. Since americium penetrates polymers much more slowly than plutonium, the penetrability of the polymer by plutonium should also be taken into consideration where both are present. The surface adsorption and penetration coefficients obtained for americium on polymers are useful as selection criteria for materials used in protective equipement.

Heat exchange in miners working in opencast ore mines in the Far North
Osobennosti teploobmena gornorabočih pri dobyče rudy otkrytym sposobom na Krajnem Severe [in Russian]
Data obtained from field observations of body heat exchange in miners doing moderately arduous work. It was found that cold work in a low relative-humidity atmosphere is linked with considerable heat loss through skin and respiratory evaporation; to these losses should be added those resulting from the warming of inspired air. To maintain the body's thermal equilibrium, it is necessary to reduce convective and radiant heat loss from skin by the use of suitable protective clothing.

Protective clothing of pure wool
Schutzbekleidung aus reiner Schurwolle [in German]
Review of the principal data concerning a protective work suit; comparison between the properties of various textiles; particularly wool. A principal feature of wool is its low flammability; it does not melt or shrink in contact with flame, affords good heat insulation and protection from flying molten metal particles, and has antistatic qualities. Woollen clothing provides a high degree of physiological comfort (maximum thermal insulation; good absorption of water vapour, but it is hydrophobic). Other advantages: wool is easy to clean and has good mechanical resistance. It satisfies all the conditions required for protective clothing against heat and flame.
